I just bought the Telltale Bundle and decided to start with the only game I didn't see before, Tales from the Borderland.
And I freaking love it! Never played Borderlands, but I really love the main characters and I'm so invested after two episodes.
I've started playing Splatoon 2 since last Friday. While I haven't truly touched the online aspects of the game, I've been searching for collectibles in Hero Mode, the game's single-player campaign. From what I've seen so far with 4 levels done and one boss down, it looks like that the mode is better thought out than the original installment did. The stages not only reminds me a lot of Super Mario Galaxy in terms of aesthetics and level structure, but the level design and the bosses (at least the first one) are top-notch.
By the way, I'm still playing Disgaea 5 Complete. About 52 hours later, I'm practically halfway done with the story mode, yet there's way more content to sink my teeth into. Of course, I could've played way faster than that, but that's because I tend to hesitate when it comes to properly raising the right stats for my characters.
